Answer:
answer is C
Explanation:
encourage the release of carbon dioxide from the stems
Answer:
Final pressure in (atm) (P1) = 6.642 atm
Explanation:
Given:
Initial volume of gas (V) = 12.5 L
Pressure (P) = 784 torr
Temperature (T) = 295 K
Final volume (V1) = 2.04 L
Final temperature (T1) = 310 K
Find:
Final pressure in (atm) (P1) = ?
Computation:
According to combine gas law method:

⇒ Final pressure (P1) = 5,048.18877 torr
⇒ Final pressure in (atm) (P1) = 5,048.18877 torr / 760
⇒ Final pressure in (atm) (P1) = 6.642 atm
2 moles of Na3PO4 form from 6.0 mol NaOH. Details about stoichiometry can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated stoichiometrically as follows:
3NaOH + H3PO4 → 3H₂O + Na3PO4
According to this equation,
3 moles of NaOH produces 1 mole of Na3PO4
This means that 6 moles of NaOH will produce 6/3 = 2 moles of Na3PO4
Therefore, 2 moles of Na3PO4 form from 6.0 mol NaOH.

Any salt, even though it reacts with water, will precipitate out completely when the water is completely evaporated. If you start with 50 grams of salt, you will end up with 50 grams of salt.
Answer the correct option will be option B.
Explanation: this is how he showed the electron could orbit the nucleus without falling into it. This is so because he explained that the electron revolves around the nucleus in a fixed circular orbit with fixed energy and cannot occupy just any energy level which is defined as quantisation of energy.
option A is one of postulates given by Dalton in his Dalton's atomic theory which later proved to be wrong.
option C it is one of the postulates given by the in J.J Thomson in his model of an atom which was the first atomic model.
option D Schrodinger has used the wave nature to explain the position of electrons around the nucleus.
